3A Switching Power Supply


Posted on Feb 6, 2014

The following diagram is the 50W offline switching power supply circuit design. The circuit powered by a MOSFET. BUZ80A/IXTP4N8 for 220V AC voltage input and GE IRF823 for 110V AC input voltage. The output will be 5VDC with electric current up to 10A. The schematic diagram: Component list: The schematic shows a 50-W power supply. Above circuit di

agram is a easy, simple and cheap switching voltage regulator which has capability to deliver adjustable voltage output range of 1. 8V to 32V and static electric current of 3A. This regulator use adjustable regulator IC of LM317HV and a power PNP transistor of 2N3792. The LM317HV is adjustable 3-terminal positive voltage regulators capable. The schematic diagram shown right here is the automatic switching-on emergency light circuit which is controlled using IC. The most important capabilities of this circuit are: automatic switching-on of the light on main power failure and battery charger with overcharge protection. When mains electrical power is absent, relay RL2 is in deenergised state, feeding DC. This is the circuit diagram of 5V Regulated Power Supply circuit, featured with over voltage protection. The circuit is based regulator chip 7805; Thyristor SCR 2N1595 and Dioda Zener 1N3997 for overvoltage protection circuit. The 5V regulated power supply is apply 74LS series integrated circuits which has to be really precise and tolerant of voltage.
